Retrobulbar anesthesia produces effective local anesthesia for ocular surgery, but significant complications have been reported with its use. To maintain its efficacy and to minimize the risks associated with the passage of a needle behind the eye, we have placed local anesthesia into sub-Tenon's space posteriorly using a blunt irrigating cannula in 100 patients undergoing vitreous or retinal procedures. Posterior Tenon's capsule is opened by blunt dissection, allowing the irrigating cannula to be passed into the posterior sub-Tenon's space for anesthetic injection. The technique was effective in 98 of 100 patients, and no morbidity was associated with its use.
球后麻醉可为眼科手术提供有效的局部麻醉，但已有使用该方法导致严重并发症的报道。为维持其有效性并尽量减少眼球后穿刺针相关风险，我们对100例接受玻璃体或视网膜手术的患者采用钝性冲洗套管将局部麻醉药注入Tenon囊后部间隙。通过钝性分离打开后部Tenon囊，使冲洗套管进入Tenon囊后间隙进行麻醉注射。该技术在100例患者中有98例有效，且未出现与该技术使用相关的发病率。
